misc: qcom: qdsp6v2: Support hardware accelerated audio effects 



Audio post processing features such as HeadphoneX are supported
only in DSP. To apply post processing for the playback which is
not routed through DSP, effects are applied through hardware
accelerated mode where PCM samples are sent to DSP for effects
processing in write path and captured by userspace through read
path.
